Fallen Hound

"These slobbering abominations are commonly found among groups of the fallen and are utilized as guard animals, beasts of burden, or even food by their demonic masters. These beasts are loyal to a fault, regardless of the abuse heaped upon them."

Fallen Hounds appear in the Battlefield of Eternity map in Heroes of the Storm, alongside Fallen Shamans. They take the place of the game's usual knight creeps. The Shaman re-summons the Hounds until he is killed.[1]
